Think of the bigger picture as you brush your teeth. Start with changing your brand of toothpaste from a commercial name to an eco-friendly option like tom's of maine, or making your own with baking soda and a few drops of cinnamon or mint oil. With most people going through four toothbrushes a year, do your part to keep plastic out of landfills by using a reusable toothbrush with a replaceable head. Always remember to turn off the faucet as you brush so save water.
